UNITED STATES ARTHUR 0. WILSON, 6F WAYNE, MICHIGAN.

RADIO CHANDELIER.

Application filed June 9,

To all whom it may concern:

Be it known that I, ARTHUR O. lVILsoN, a citizen of the United States, residing at Jayne, in the county of Wayne and State of hilichigan, have invented new and useful Improvements in Radiochandeliers, of which the following is a specification.

This invention relates to electric lighting fixtures, particularly to chandeliers of the dome type, and has for its object the provision of a novel chandelier having built thereinto the amplifying horn of a radio loud speaker, the advantage being that this device will obviate the diiiiculties encountered in the use of the ordinary and wellknown loud speakers which have their independent horns and which are frequently diflicult to place conveniently in a room and which are always more or less of an eye sore.

Another object is the provision of a chandelier of the combined type specified which will do away with unsightly wiring strung around in the way.

The invention further contemplates the provision of a chandelier or dome which is provided with internal means for illuminating a ventilating space therein, the illumination being visible through slots, trans parent areas or the like in the dome itself so as to create an unusual and pleasing effect.

An additional object is the provision of a chandelier or dome fixture which will be comparatively simple and inexpensive in manufacture notwithstanding its combination qualities, which will be efficient and durable in use, and a general improvement in the art.

\Vith the above and other objects and ad- 'antages in View, the invention consists in the combination and arrangement of parts to be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which:

Figure 1 is a side elevation of the device.

Figure 2 is a bottom plan view thereof.

Figure 3 is a central longitudinal section.

Figure i is a detail section on the line -l& of Figure 8.

cap 10 constructed of any suitable metal and of a size and shape to conformingly engage about the plate or board B and this cap is adapted to be mounted by means of screws or their equivalent. Extending through and projecting below the cap 10 is a series of posts 12 having flanges 13 thereon bearing against the underside of the cap and having their upper ends threaded. and carrying nuts 1a which effect the clamping action. These posts are of tubular formation in order to serve as conduits for the current carrying wires 15 which are led to the various lamps to be described, and it is obvious that these wires are brought up through the usual conduit 16 which extends through the ceiling so that these wires can be connected with the house wiring. The lower ends of the posts 12 are formed with flanges 17 and their extremities are threaded.

The invention further includes a shelllike dome 18 which is here represented as having a general rectangular shape but which could of course be of any other desired configuration. The material from which this dome or shell isconstructed may glass, either translucent or opaque, porcelain, or in fact anything else suitable. Secured in any preferred manner within, or formed integrally upon or with the top portion of the shell or dome, is a plate 19 through which the lower ends of the posts 12 extend, and securing is effected by means of nuts 21 threaded onto the extremities of the posts, which nuts eo-operate with the flanges 17 for effecting the necessary clamping action. At the lower edge of the dome or shell is frame structure 21 formed with a depending skirt 22 which may be made as ornamental as desired. In fact, this entire dome device might be molded from a single piece of glass or the like, or it might, if favorable, be constructed of suitable sections or pieces cemented or otherwise fastened together, depending upon the nature of the material. In the present instance I have illustrated the shell or dome as formed at points with openings 23 covered with screen 24 mounted on finishing rings 25, and I have also shown a series of ornamental beads or moldings 2G and slots or transparent or translucent narrow areas 27 so as to permit light to pass from the interior through the dome to produce a more attractive effect.

Secured in any desired manner upon the corner portions of the shell or dome are brackets 28 carrying sockets 29 for incandes cent bulbs and also carrying suitable shades The essential feature of the invention lies in the pro-vision of an amplifying or loud speaking horn31 which is located within the shell or dome 18 with its month end located at the frame 21. The exact shape, construction and material from which this horn is formed may of course vary within wide limits though I have illustrated the small end as having an outstanding flange 32 between which and the plate 19 is interposed a felt or other gasket 33. The horn is secured in place by bolts 34 which pass through the flange 32, the gasket 33 and the plate 19 and which carry nuts 35 of any desired type. The plate 19 is formed centrally with a hole 36 communicating with the small end of the horn, and arranged upon the top of the plate 19 is a loud speaker unit 37 which extends into the opening 36 and which is of course connected by the wires 38 with the output from any suitable radio receiving set, not shown.

For holding this loud speaker unit in operative position upon a packing gasket 39 engaging against the plate 19, I provide a sleeve or socket 40 having a flange 41 secured at the center of the underside of the cap 10. Slidably engaged within this socket or sleeve is a plunger 42 terminating in a disk 43 from which project legs or feet 44 equipped with elastic caps or pads 45, which bear upon the top of the loud speaker unit 37. A spring 46 surrounds the socket 40 and plunger 42 for urging the latter downwardly into firm clamping engagement wit-h the loud speaker unit so that the latter will be held firmly in position and be prevented from casual displacement.

The horn 31 is of such size and shape as to provide quite a large space 47 between it and the dome or shell, which space serves for ventilating purposes. Located within said space is an incandescent bulb 48 held within a socket 49 carried by a bracket 50 mounted on the inner wall of the shell or dome. The purpose of this bulb is to illuminate the space between the horn and the.

dome so that the slots or transparent areas 2'? and the openings 23 will be illuminated, thereby taking away the hard opaqueness of the device. However, if preferred, the entire dome might be constructed from or provided with panels or opalescent or translucent glass or other material so that the attractiveness would be still more enhanced. While is is not absolutely necessary, I have shown the socket 49 as equipped with a pull chain 51 facilitating the control.

Extending transversely through the upper portion of the horn, is a rod or spindle 52 having its ends engaged sleeves 53 on the opposite sides of the horn. This transverse member is prevented from longitudinal movement by cotter pins 54 or the like. Extending through the center of this transverse member is an eye-bolt 55 from which is suspended a chain 56 carrying a socket 57 for the incandescent bulb within a globe or shade 58. This socket, as well as the sockets 29, is represented as being of the key type. The exact wiring to the various sockets is shown but need not be described in detail as it is conventional and obvious.

lVhilc I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as within ferrules or will not depart from the spirit of the invention or the scope of the subjoined claims.

A combination fixture comprising a supporting cap, a dome mounted beneath and hung from the cap and carrying sockets for incandescent bulbs, an amplifying horn mounted within the dome and secured to the top thereof, a loud speaker unit mounted upon the top of the dome in communication with the small end of the horn, and a downwardly urged clamp engaging the unit including a. socket on the cap, a plunger slidable through the socket and having padded feet engaging the unit, and a spring urging the plunger downwardly.
